. Computation procedures are needed to estimate losses of sediment, pesticides and nutrients from agricultural fields to surface water. The long-term objective of the proposed research is to develop an improved contaminant load calculation procedure for agricultural watersheds. Geostatistics can be used to obtain accurate load estimates. The short-term objective of this research is to develop and validate a geostatistical model to improve the calculation of sediment and nutrient loads. The originality of the proposed research resides in the development of a load calculation procedure using kriging techniques and statistical relationships that have not, so far, been used at their full potential.

. 需要有计算程序来估计沉积物、农药和营养物从农田流失到地表水的情况。建议的研究的长期目标是开发一个改进的农业流域污染物负荷计算程序。地统计学可用于获得准确的负载估计。本研究的短期目标是开发和验证地质统计学模型，以改进沉积物和营养物负荷的计算。所提出的研究的独创性在于使用克里格技术和统计关系的负荷计算程序的开发，到目前为止，还没有充分利用它们的潜力。
