Abstract

This research was done to study the applicability of KINEMATIC WAVE approach in design of FLOOD SPREADING systems and simulation of overland flow over spreading plots. To this, KINEMATIC WAVE model was studied and was used to simulate the advance phase. It was assumed that flood-spreading plots have no transversal slope and water flows down stream in direction of longitudinal slope as sheet flow. Therefore, one dimensional shallow water flow equation could be applied. PRIESSMAN BOX SCHEME with an iterative method for time adjusting was selected to discretize the governing equations. To verify and evaluation of the model, three analytical and two numerical models as well as observations were used, respectively. Unfortunately, there was no recorded information about flow on FLOOD SPREADING plots, to evaluate the model. So, observed data of 31 borders were used to different modeling procedures. Seven borders were omitted from analyses for the lack of accuracy, because of non-kinematic behavior of them. Five borders were used for sensitivity analysis and calibration. The remaining 19 borders were used to evaluate the model. Analyses showed that the model has no sensitivity on time step and time weighting factor of PRIESSMAN BOX SCHEME. Average relative error and prediction efficiency were, 7.8 and 99.45 percent, respectively.
