Assessing the variation of river channel reach inflows on transmission losses

Abstract Arid and semi‐arid regions are characterized by limited water availability throughout the year highly variable streamflows. River channel transmission losses add another uncertainty to complex flow regimes. However, contribution of different factors influencing is poorly understood. In this work we determined whether variations in river along five reaches varying lengths could be related reach inflows Runde catchment Zimbabwe. We directly estimated as difference between inflow outflow discharges. Using simple bivariate regression equations, were modeled response variables while predictor variables. Our results indicate statistically significant positive relationships ( p = .000, R 2 > 0.05) for all minor, moderate, major events. This approach can applied similar settings understand losses.
