27370 - Hydraulic Agro-Forestry

Learning outcomes

To provide tools for landscape survey and analysis, giving a startpoint for handling soil and water conservation issues, in an approach integrated with the environment and its hydrological, hydraulic and geomorphologilal aspects.

Course contents

Surface runoff erosion , slope instability, mass movement

Geotechnics characterisation rocks versus water.

Soil loss predictions , modelling soil erosion, Universal Soil Loss Equation

Action of watercourses . Surface water circulation. Hydrography and patterns of stream drainage area Elements of fluvial hydrology

Water flow, measurement methods. Coefficient of discharge

Modes of transport: suspension, traction and solution

Sediment yield from river basin. Basin water balance, drainage coefficient.

Discharge hydrograph, characteristic curves

Study of precipitation and water flow extremes for the design of fluvial engineering works: climate possibility distributions, Gumbel statistical analysis, storm return time
