“…The model uses finite differences to solve the partial differential equations that depict the movement of water flow while simulating each distinct sub-module. The connection between the MIKE SHE model and the MIKE 11 model is established through the use of river linkages (MIKE SHE links) [29] . These links allow for the simultaneous simulation of the flow between surface water and groundwater, enabling the two models to be connected.…”

Climate change and human activities both have a considerable impact on runoff depth, which are important parts of a changing ecosystem. Nevertheless, the main focus of hydrological response research has been on investigating the impact of climate change on the depth of runoff. In contrast, there has been limited emphasis on comprehending the precise mechanisms through which changes in land use, in relation to human activities, influence runoff depth. This paper utilized the MIKE SHE/MIKE 11 model to simulate the runoff depth process in the study area from 1980 to 2020. It estimated the influence of climate change and land use change on runoff depth using the runoff reduction method. Additionally, it quantified the impact of different land use changes on runoff depth by employing the spatio-temporal geographically weighted regression model. The study demonstrates that the MIKE SHE/MIKE 11 model is capable of accurately reproducing the runoff depth of the Songnen Plain. Both the R and NSE values for both the base and validation periods exceed 0.75. Moreover, from a geographical standpoint, climate change has a greater influence on runoff depth than human activity. Nevertheless, the impact of human activity is more evident in small, specific areas. As human activities intensify, their impact on runoff depth also increases, with the average contribution rising from 20% to over 30%. Changes in various land types within the watershed can be used to observe the influence of human activities on runoff depth. More precisely, a 10% rise in the rate of change of construction land, dry land, and unoccupied land results in an increase in runoff depth of 6.21 mm, 2.45 mm, and 1.14 mm, respectively. Conversely, a 10% rise in the rate of alteration of marsh, paddy, and forest land leads to a reduction in the depth of runoff by 9.49 mm, 6.46 mm, and 3.07 mm, respectively. This research can contribute to improving the efficiency of water and land resource utilization and optimizing land resource governance.

“…Integrated hydrological models can simulate hydrological processes occurring on the surface and subsurface at a wide range of spatial and temporal scales (Paudel and Benjankar, 2022). Especially, the approach integrates hydrodynamic models to simulate river hydraulics, water quality, sediment transport, floods and forecasting changes in surface flows.…”

Currently, in the world, there are many different hydrological models built and developed to solve problems related to the hydrological cycle. Each model has its specific mathematical foundations to describe physical processes in nature. Therefore, each model has its various characteristics: setting up the model, input data requirements, model calibration and verification, and output results. Water balance is still playing an important role in the effective management and use of water resources for agriculture. Based on the results of the hydrological parameter’s calculation, the water balance of the study basin can be calculated by the user or by the separated module of each model. Each hydrological models have its advantages and disadvantages. However, it is impossible to simulate hydrological processes and water balance completely accurately in nature. Still, simulation results can give us a view of the changing trend of hydrological components and the water balance. Model developers are gradually completing the shortcomings and improving the efficiency and accuracy so that the model can simulate reality with the highest accuracy. This paper sets out to review the fifteen hydrological models currently widely used in the world. Within the frame of the present study, some models are only briefly introduced; the rest are considered in more detail, from more aspects, from specific examples so that readers can decide for themselves which model is suitable for their study area and simulation needs, especially in the identity of the complex and unpredictable impacts of climate change on the agricultural sector.

Stability in time of major and important objectives is vital and can be achieved by 3D scanners which follow changes in time with construction, respective of the natural or artificial hydrotechnical dams and the obtaining of 3D data in real time with the possibility of evaluating and making quick decisions. This scientific paper approaches a research topic of great importance and actuality in the field of Civil Engineering, Hydrotechnics, and Geomatics using the 3D scanning technologies for the hydrotechnical arrangements (Topolovăţu Mic, Coșteiu and Sânmartinu Maghiar) and hydroameliorative (Cruceni Pumping Station). In Romania, data collection was carried out for the first time using the mobile scanning technology (MMS), “Backpack” type, namely, Leica Pegasus Backpack. Data collection using terrestrial laser scanning technology (Terrestrial Laser Scanning) was carried out with the Leica C10 equipment. The processing of point clouds was carried out using the Inertial Explorer program, and the processing of point clouds was carried out with the Cyclone program. The collection of ground checkpoints used for checking, correcting, and analyzing point clouds was carried out using the GPS Leica GS08 equipment. Compared with traditional methods using classical measuring instruments, precise data was obtained (with an error of 2–4 cm) through 3D laser scanning technology in a short time and with multiple possibilities of processing and visualizing point clouds.
