大石河漫水河站“7·21”与“7·20”暴雨洪水对比分析

通过对北京市2012年“7·21”和2016年“7·20”等2场暴雨成因、过程、特征以及洪水过程、特点的分析,发现“7·20”暴雨降水总量大于“7·21”,但洪峰流量接近,径流系数偏小,洪水水位偏低,主要是由于“7·20”暴雨历时长、强度小以及河道整治等因素造成的,导致土壤入渗比例增大、洪水过程平缓.本项研究对进一步认识大石河漫水河站以上流域水文特征、提高水文预报精度以及防汛调度具有一定的参考价值.     

“96·7”特大暴雨洪水剖析及灾后反思

“96·7”特大暴雨洪水是湖南省超历史纪录的洪涝灾害，暴雨天气系统之复杂，暴雨强度之大，范围之广，洪峰水位之高以及受灾面积之大，灾害损失之严重是触目惊心的。通过对“96·7”特大洪灾的反思，给我们今后治理洞庭湖区提出新的思路。

Reproductive success of the interior least tern (Sterna antillarum) in relation to hydrology on the Lower Mississippi River

The annual hydrograph of large rivers, including flood pulses and low‐flow periods, is believed to play a primary role in the productivity of biota associated with these ecosystems. We investigated the relationship between river hydrology and Interior least tern (Sterna antillarum) reproductive success on the Lower Mississippi River from April to July 1986–1993. The number of fledglings produced per adult pair was negatively correlated with July mean (r=?0.95, p=0.0004) and July maximum river elevation (r=?0.97, p=0.0001), but no other aspects of river hydrology were related to tern reproduction. Low‐water elevations in July may benefit least tern reproductive success by increasing sand island area or the area of shallow‐water habitat that surrounds islands. Loss of deep‐water habitats in conjunction with an increase in shallow habitat during stage decreases may concentrate fish prey in shallow‐water habitats and backwater areas, thereby increasing food availability during chick‐rearing.

Warming of the lower Columbia River, 1853 to 2018

Water temperature is a critical ecological indicator; however, few studies have statistically modeled century-scale trends in riverine or estuarine water temperature, or their cause. Here, we recover, digitize, and analyze archival temperature measurements from the 1850s onward to investigate how and why water temperatures in the lower Columbia River are changing. To infill data gaps and explore changes, we develop regression models of daily historical Columbia River water temperature using time-lagged river flow and air temperature as the independent variables. Models were developed for three time periods (mid-19th, mid-20th, and early 21st century), using archival and modern measurements (1854–1876; 1938–present). Daily and monthly averaged root-mean-square errors overall are 0.89°C and 0.77°C, respectively for the 1938–2018 period. Results suggest that annual averaged water temperature increased by 2.2°C ± 0.2°C since the 1850s, a rate of 1.3°C ± 0.1°C/century. Increased water temperatures are seasonally dependent. An increase of approximately 2.0°C ± 0.2°C/century occurs in the July–Dec time-frame, while springtime trends are statistically insignificant. Rising temperatures change the probability of exceeding ecologically important thresholds; since the 1850s, the number of days with water temperatures over 20°C increased from ~5 to 60 per year, while the number below 2°C decreased from ~10 to 0 days/per year. Overall, the modern system is warmer, but exhibits less temperature variability. The reservoir system reduces sensitivity to short-term atmospheric forcing. Statistical experiments within our modeling framework suggest that increased water temperature is driven by warming air temperatures (~29%), altered river flow (~14%), and water resources management (~57%).

Assessing Juvenile Native Fish Demographic Responses to a Steady Flow Experiment in a Large Regulated River

The Colorado River below Glen Canyon Dam, Arizona, is part of an adaptive management programme which optimizes dam operations to improve various resources in the downstream ecosystem within Grand Canyon. Understanding how populations of federally endangered humpback chub Gila cypha respond to these dam operations is a high priority. Here, we test hypotheses concerning temporal variation in juvenile humpback chub apparent survival rates and abundance by comparing estimates between hydropeaking and steady discharge regimes over a 3‐year period (July 2009–July 2012). The most supported model ignored flow type (steady vs hydropeaking) and estimated a declining trend in daily apparent survival rate across years (99.90%, 99.79% and 99.67% for 2009, 2010 and 2011, respectively). Corresponding abundance of juvenile humpback chub increased temporally; open population model estimates ranged from 615 to 2802 individuals/km, and closed model estimates ranged from 94 to 1515 individuals/km. These changes in apparent survival and abundance may reflect broader trends, or simply represent inter‐annual variation. Important findings include (i) juvenile humpback chub are currently surviving and recruiting in the mainstem Colorado River with increasing abundance; (ii) apparent survival does not benefit from steady fall discharges from Glen Canyon Dam; and (iii) direct assessment of demographic parameters for juvenile endangered fish are possible and can rapidly inform management actions in regulated rivers.
