Displacement prediction plays a significant role in the landslidedisaster early warning. However, landslide deformation is a complex
nonlinear dynamic process, posing difficulties in the displacement
prediction especially for the commonly used static models. This study
applies an advanced deep machine learning method called gated recurrent
unit (GRU) to the displacement prediction of the Jiuxianping landslide,which is a typical reservoir landslide located in the Yunyang County of
Chongqing, China. Results show that the GRU-based approach is able toportray the variation of the periodic displacement in the testingdataset with fewer outliers. Although both the artificial neural network(ANN) and random forest regression (RFR) can capture the variation
tendency of data points in the training dataset, they are unable topredict the local peaks well in the testing dataset. For themultivariate adaptive regression splines (MARS), the deformation
characteristics of the periodic displacement curve cannot be well
captured, and the overall predictive performance is unsatisfactory.
Different from the three static models, the GRU model is essentially adynamic model making full use of the historical information, which canportray the deformation characteristics of the Jiuxianping landslide
rationally.

Table Rock Lake was completed in 1958 on the White River in southwestern
Missouri and northwestern Arkansas for flood control, hydroelectric
power, public water supply, and recreation. The surface area of Table
Rock Lake is about 42,400 acres, and about 715 miles of shoreline are at
the conservation pool level (915 feet above the North American Vertical
Datum of 1988). Sedimentation in reservoirs can result in reduced water
storage capacity and a reduction in usable aquatic habitat; therefore,
accurate and up-to-date estimates of reservoir water capacity areimportant for managing pool levels, power generation, recreation, anddownstream aquatic habitat. Many of the lakes operated by the U. S. Army
Corps of Engineers are periodically surveyed to monitor bathymetricchanges that affect water capacity. In October and November 2020, theU.S. Geological Survey, in cooperation with the U. S. Army Corps ofEngineers, completed one such survey of Table Rock Lake using a
multibeam echosounder. The echosounder data were combined with U. S.
Geological Survey 1/3 arc-second digital elevation model data and lightdetection and ranging (lidar) data, where present, to prepare abathymetric map and a surface area and capacity table up to the flood
pool elevation of 931 feet above the North American Vertical Datum of
1988.
