Dr. Ramesh Rudra has more than 40 years of research experience as a researcher and an educator.

As a researcher my research activities focus on agricultural watershed management (concepts/processes and modelling) of field and watershed processes, as evident by more than 110 refereed journal publications, more than 60 refereed proceeding publications and more than 500 presentations at scholarly conferences, workshops and symposia in Asia, Europe and North America. More than 70 (10 Ph.D. and 70 M.Sc. and M. Eng.) graduate students from Canada, Asia, Africa, Far East, Middle East, South America, Central America and South-east Asia  have successfully completed their thesis research on agricultural water management related to their countries under his supervision.

The main focus has been on watershed management, water budgeting and source water protection for water quantity, quality and non-point source pollution.  Processes of soil erosion, infiltration, irrigation and drainage. Modelling and management of non point source pollution. This includes modelling of infiltration, surface and subsurface drainage, overland flow, soil erosion by water, sediment transport, sediment and pollutants  (nitrogen, phosphorus and pathogens) transport through vegetated areas along the stream, quality of surface and tile drainable water as affected by manure, nutrients and pesticides. Water harvesting by rainfall runoff inducement, seepage control and evaporation reduction. The present research focus is on water budgeting, variable source area hydrology, change in precipitation and temperature regimes due to climate change and their impact on agricultural water management, the development of tools for source water protection, watershed management and  design of vegetative filter strips based on the characteristics of upland watershed or characteristics of runoff water to manage stream water quality, and for estimation of Total Maximum Daily load (Pollutant loads a water body can accept with impairment). I am involved in the development advisory tools such as Phosphorus Index and Nitrogen Index,, to identify appropriate practices to manage agricultural water quality.

Watershed System Capacity: Development of tools to assess water quantity and quality and identify opportunities to improve it in watersheds including consideration of the watershed system capacity  to absorb contaminants, as well as the quality of water relative to its use by various sectors and techniques  to identify sources of contaminants, evaluation of social acceptability (barriers) and economic feasibility. Development of BMPs to reduce the risk of soil degradation, pollution of drainabe water and development of improved tools and decision support systems, for source water protection. Development of educational and technological transfer tools to improve watershed management by rural agro-food industries.  Most noticeable research includes the development of modelling tools (GAMES/GAMESP, GDVFS, AGNPS-GDVFS tool kit), the procedure for evaluation of hydrology and nonpoint source pollution models, temporal variability in soil erosion and hydraulic characteristics, experimental procedures for variable source area hydrology, targeting and multi-tier approaches for watershed management, use of waste water in agriculture and simple tools for identification of climate change. In addition, he has been providing technical assistance to extension agents, officials in the public and private sectors in planning, design, development, management and evaluation agricultural management systems related to irrigation, drainage (both surface and sub-surface), soil erosion and non-point source pollution control.

Water Quantity: This work focus on the development of water resources in the arid and dryland regions of India by rainfall runoff inducement, seepage control and evaporation reduction in earthen rural reservoirs estimation of rural and agricultural (irrigation and livestock) water demand and design of water distribution systems.  Water quality research is also related  to water problems in arid areas including the use of domestic waste water rich in surfactants  in irrigation and its impact on soil quality. The other work on water quantity focused on the assessment of various components of water budget (surface water and ground water) and their temporal variability.

Water Quality: The focus of my water quality work has been on sediment , phosphorus, Nitrogen, Pesticide and pathogens from rural and agricultural point and nonpoint sources. I have been involved in the development of tools, applicable at the farm,. field and agricultural watershed for the identification of sources of runoff, ground water recharge and pollution, their contribution to the flows and water quality at the watershed outlet or to the reservoir, selection of BMP for the improvement of water quality to meet water demand, development of remedial strategies and monitoring programs. At present, my research is focusing on the development of tools for the identification of variable source (runoff generating and ground water recharge areas), design of vegetative filter strips along the stream based on the characteristics of the upland runoff (originating from non-point and distributed rural point sources). The water quality indicators being evaluated are sediment, phosphorus, nitrogen and coliform bacteria. The new directions being includes development of system capacity for a water body for a particular pollutant without impairment of water body. The present focus is on phosphorus, nitrogen, pesticide and pathogens. In the future the focus will be extended tobio-aerosols, hormonally active compounds, antibiotics and heavy metals. I have been involved in the development management models for farm planning and agricultural watershed planning.

RESEARCH/CONCEPTS/PROCESSES/PRODUCTS/TECHNOLOGIES

New Concepts and/or Processes
Temporal Variation in Soil Hydraulic and Erosion Characteristics:  In early 80’s’ this research group introduced the concept of temporal variability of soil erodibility and hydraulic characteristics of soil (Saturated hydraulic conductivity), which were later incorporated in the new approaches (field and watershed scale models) of hydrology, soil erosion, sediment transport, drainable water quality and non-point source pollution.
Targeting Approach for Agricultural Watershed Management: During late 80’s and early 90’s this group introduced the concept of identification of source of soil erosion and fluvial sedimentation in water shed for the development of remedial strategies and implementation of beneficial management practices to manage soil erosion, sediment  and nutrient transport from agricultural watersheds. This approach has been and being used for agricultural watershed management.
Mutli-Tier Watershed Management Approach: During late 90’s, this research group proposed a multi-tier approach for agricultural watershed management. The approach involves identification of a watershed management issue/problem, selection or development of simple conceptual tool (model) suitable for the exploration of the issue/problem identified and appropriate to the database available, and application of the tool to address the identified issue/problem. The procedure is repeated by increasing the complexity in the conceptual tool until the identified issue/problem has been addressed satisfactorily. This approach is now used by many soil and water management agencies.
Procedure to Identify Sources of Runoff, Erosion and Pollution: This research group has developed an experimental procedure of WSN (wireless sensor network) comprising runoff sensor and wireless recording system to identify field in a watershed generating runoff and their contribution to the flow at the watershed outlet. This work is still in progress.

Research Contributions

Hydrologic and Nonpoint Source Pollution Processes: For the process research the most significant contributions have been the introduction of concept of temporal variations in soil erosion and hydraulic characteristics. This concept has been now adopted in new modelling approaches. The significant contributions also include the mechanics and spatial variability of runoff generation areas within a rainfall event, from event to event, and season to season. The contributions also include the evaluation of fractural structure of soil physical characteristics (soil texture, total porosity and bulk density) and hydraulic, hydraulic characteristics (saturated hydraulic conductivity and effective suction at the wetting front), including evaluation of techniques for spatial interpolation. The other contributions include development of procedure for identification of base flow and/or surface runoff dominated watersheds based on hydrologic soil groups, soil drainage characteristics and depth of bed rock. This procedure has potential application in watershed based source water protection and nutrient management.

Model Development and Model Application: The most significant contributions have been the targeting concept in the development of remedial strategies and a multi-tier objective oriented approach for nonpoint source pollution management. These approaches are used for the evaluation of effectiveness of Best Management Practices. The significant contribution also includes the development of GDVFS, a modeling toolkit, for site specific design and evaluation of vegetative filter strips. This approach is being extended to evaluate the performance of vegetative filter strips in a watershed context. The other significant contributions include the development of Variable Source Area model. These approaches are now used in the management of soil erosion and nonpoint source pollution. The Guelph group has national and international reputation in modeling of pollution from agricultural nonpoint agricultural sources.

Development of Field Methodology: During last few years one of the foci of the research has been the development of field experimental procedures for hydrologic process research. Two experimental procedures developed include methodologies for field evaluation of the performance of vegetative filter strips and identification of spatial distribution of runoff generating area. The monitoring of runoff generation procedure focused on the development of low cost wireless sensor network (WSN) consisting runoff sensors and a wireless recording system for continuous monitoring of runoff and soil moisture at various locations in a watershed. These technologies are now being applied to identify runoff contributing areas and identification of location of BMP’s in watersheds, and has the potential application in source water protection (identification of groundwater recharge areas) and nutrient management (Phosphorus Index).

Change in Precipitation and Temperature Regimes: The significant contributions include the identification of changes in short term rainfall extremes, temperature and winter precipitation regimes in Ontario. The positive and negative changes in annual rainfall extremes are similar in the order of magnitude. The change in trends between shorter duration and longer duration are similar; however, the change in trends among the shorter and longer durations are different. There is no obvious spatial pattern with possible exception of positive trends at north-western region. The changes in monthly extremes for the months of April and May in the northwest region are negative; the May and October extremes in the southwest region and the April and May extremes in the southeast region are positive. The changes in August extremes for the southwest and southeast regions are negative. Over the winter period the minimum daily temperature and snowfall are decreasing, and number of frost free days and winter rainfall are increasing. The change in rainfall intensity, duration and frequency (IDF) pattern is very similar to the change in rainfall extremes. The percentage changes in IDF values for the period of Pre ’80 (i.e., ’60 to ’79) to the period of Post ’80 are approximately double the percentage change in change per decade values. The percentage changes in IDF from Pre ’60 to Post ’80 reveal dramatic declines for most duration at almost all around Ontario.
