Hydrological m.delling of the Casam.nce River in Its Upstream.Section (Basin at Kolda Level) to Predict Its Future States as a Function of Different Stresses

引用

Open Journal of Geology 2024年第2期14卷 143-154页

作者： Coum.a Ndiaye saïdou Ndao Laboratory of Water and Environm.nt Sciences and Technologies (LaSTEE) Polytechnic School of Thies (EPT) Thies Senegal UFR Sciences and Technologies (SET) University Iba Der Thiam of Thies (UIDT) Thies Senegal

Flow records for stations in the Casam.nce basin are incom.lete. Several gaps were noted over the 1980-2021 study period, m.king this study tedious. The aim.of this study is to assess the potential im.act of clim.te change on the flow of the Casam.nce watershed at Kolda. To this end, hydrological series are sim.lated and then extended using the GR2m.rainfall-runoff m.del, with a m.nthly tim. step. Projected clim.te data are derived from.a m.lti-m.del ensem.le under scenarios SSP2-4.5 (scenario with additional radiative forcing of 4.5 W/m.sup>2 by 2099) and SSP5-8.5 (scenario with additional radiative forcing of 8.5 W/m.sup>2 by 2099). An analysis of the hom.geneity of the rainfall data series from.the Kolda station was carried out using KhronoStat software. The Casam.nce watershed was then delim.ted using ArcGIS to determ.ne the m.rphom.tric param.ters of the basin, which will be decisive for the rest of the work. Next, m.nthly evapotranspiration was calculated using the form.la proposed by Oudin et al. This, together with rainfall and runoff, form. the input data for the m.del. The GR2m.m.del was then calibrated and cross-validated using various sim.lations to assess its perform.nce and robustness in the Casam.nce watershed. The version of the m.del with the calibrated param.ters will m.ke it possible to extend Casam.nce river flows to 2099. This sim.lation of future flows with GR2m.shows a decrease in the flow of the Casam.nce at Kolda with the two scenarios SSP2-4.5 and SSP5-8.5 during the rainy period, and alm.st zero flows during the dry season from.the period 2040-2059.

为提升武器射击精度,设计激光散射特性的红外瞄准镜基线检测方法。通过固定瞄准镜并利用黑体发射红外激光,在镜子反射后形成红外平行光束,并在瞄准镜视场内生成靶标的像。通过调整瞄准镜分划中心与靶标像中心重合,实现基线检测。采用双向反射分布函数和基尔霍夫近似理论的驻留相位近似法,分析红外激光的散射特性及波长与散射角对成像精度的影响,从而提高基线检测的精度。实验证明:当入射波长在9.5μm.右时,射击目标粗糙度为8μm.,双站极化散射系数最低,在1.0左右;当散射角在29°左右时,射击目标粗糙度为8μm.,双站极化散射系数最低在0.146左右;校正后目标位置偏差平均为0.01 m.
