AN EVALUATION OF TWO TEN-YEAR SEDIMENT BUDGETS, NAHAL YAEL, ISRAEL

摘要: The method used to derive a crude ten-year sediment budget for Nahal Yael—a small hyper-arid catchment in the Southern Negev Desert—is applied later period, which much more accurate is available. Results indicate that of first decade has overestimated suspended output by factor four, and underestimated bed material two. Evaluated against background similar studies, it concluded main source potential errors budgets, especially those involving considerable amounts material, lies not so volumetric before-after comparisons, based on surveying. Rather, are caused mainly inadequate procedures presently available estimation input into, from, studied reach.
