Monitoreo y análisis comparativo de metodologías para la determinación de la erosión hídrica en una parcela experimental

Abstract

The processes of water erosion and, consequently, the geomorphological modifications, occur naturally, achieving a ciinámico balance that many times is influenced by the actions of the man, accelerating the normal movement of sediments and consequently, modifying the profiles of drainage and its configuration. Many of these processes and their responses are not linear and have great variability in space and time, so that the forecast of erosions through methods based on numerical analysis or experimental analysis is a very important tool for the Time to plan and design engineering works. The problem of erosion and deposition of cohesive soils by water action is important from the point of view of engineering, because it is related, among others, to the stability of canals with cohesive beds, to the stability of surface drainage works (bridges , Culverts, gutters, etc.), with the maintenance of lower depths in estuaries (where the sediment is deposited to a greater extent) and with the useful life of the reservoirs. In the present study, the soil loss per unit area (t x ha - I x year ') measured in 3 experimental plots, whose location, construction and monitoring is described in chapter I of this document, is related to the soil loss. This loss of soil was measured in the field by using devices called experimental stations. Its monitoring period comprised five months of the rainy season of our city; Which allowed us to determine the loss of soils in the field.
