Catchment Management

Program Overview

This five-day course at Cranfield University delves into catchment hydrology and hydraulics, focusing on water quantity and quality management. Participants will learn to evaluate sediment and pollutant sources, design drainage systems, and implement soil erosion control measures. The program includes case studies and is led by Dr. Robert Simmons.

What you will learn

On successful completion of this course you will be able to:

• Critically evaluate sources of sediment, nutrients and pesticides within a catchment, their pathways and receptors and identify management options
• Select appropriate input parameter values to apply soil erosion models to predict current erosion status and evaluate different soil conservation measures to control both water quality and quantity,
• Design drainage systems, channels/ waterways and simple hydraulic structures including the calculation of peak runoff and total yield for a catchment,
• Devise preventative and remedial techniques to improve catchment water quality, taking account of site location within a catchment and socio-economic conditions,
• Explain the interactions of irrigation with catchment management and quantify crop water requirement.
