WATERSHED MODELLING AS A FUNCTION OF GEOTECHNICAL INVESTIGATIONS
Abstract
Methods of estimating yield from ungaged watershed may be by using of climatic factors, only geographic location and watershed and climatic factors. Methods for estimating yields, as regional analysis, water accounting, direct runoff method, climatic and geographic factors, should be considered as giving estimates so broad that the influence of specific factors have large margins or error. Hydrologic simulation models in watershed modelling use mathematical equations to calculate results like runoff volume or peak flow. Those models can be classified as either theoretical or empirical models. A theoretical model includes a set of general laws or theoretical principles. Further, depending on the character of the results obtained, models are classified as stochastic or deterministic. In this paper are analysed methods for estimating yields, event versus continous models (empirical model, linear system transfer functions, explicit moisture accounting modelconceptual, physical process model) and generalities of watershed models (hydrodynamics and water quality of land surface runoff, groundwater and freshwater hydrodynamics and water). Purpose and scope are in procedure and methods for conducting geologic investigations related to sedimentation, engineering geology, and groundwater for work plan development.
