“…The strong relationship between SubUHI and surface landcovers has been noticed in previous studies. , The relation between the SUHI and SubUHI at a certain depth is similar to that between the SubUHIs at two different depths. The relations between the SubUHI and SUHI are illustrated from the following three aspects: On the intensity: The SUHI and shallow-layer (0 < z < 0.5 m) SubUHI intensities both vary diurnally but the SubUHI intensity at a greater depth has a less significant variation during a DTC.…”

“…The soil temperatures at these three layers are correspondingly impacted by surface climate approximately related to centenary, decadal, and annual cycles, respectively. At the very-deep layer, subsurface temperatures measured in deep boreholes are good indicators of historical surface climate , and land cover change, particularly, the urbanization . At this layer, the SubUHI develops over time scales of a century or more. − At the deep layer, Ferguson and Woodbury indicated that the relationship between soil temperature and surface processes is complex.…”

The subsurface urban heat island (SubUHI) is one part of the overall UHI specifying the relative warmth of urban ground temperatures against the rural background. To combat the challenge on measuring extensive underground temperatures with in situ instruments, we utilized satellite-based moderate-resolution imaging spectroradiometer data to reconstruct the subsurface thermal field over the Beijing metropolis through a three-time-scale model. The results show the SubUHI's high spatial heterogeneity. Within the depths shallower than 0.5 m, the SubUHI dominates along the depth profiles and analyses imply the moments for the SubUHI intensity reaching first and second extremes during a diurnal temperature cycle are delayed about 3.25 and 1.97 h per 0.1 m, respectively. At depths shallower than 0.05 m in particular, there is a subsurface urban cool island (UCI) in spring daytime, mainly owing to the surface UCI that occurs in this period. At depths between 0.5 and 10 m, the time for the SubUHI intensity getting to its extremes during an annual temperature cycle is lagged 26.2 days per meter. Within these depths, the SubUHI prevails without exception, with an average intensity of 4.3 K, varying from 3.2 to 5.3 K.

This study aims to determine the physiographic characteristics according to the slope, land use, and runoff that affect water control in the Benowo area, Surabaya. From the comparison of the results of the runoff in the dry season and the rainy season there was an increase in the average runoff value from 24 % to 26 %. Although there is a difference in the value of the runoff of 2 %, this can affect the increase in water runoff above the surface of the study area. The value of the runoff in the study region will be significantly impacted by changes in land use from agriculture and water to residential or industrial areas. The runoff predicted data’s overall accuracy value for both dry and wet seasons is good, and the Cohen’s kappa value is almost a perfect consistency. The overall accuracy value is 89.7% in the wet season compared to 87.4% in the dry season. During the dry season, the Cohen’s Kappa value is 83.8%, and during the rainy season, it is 86.6%. The result of this research is a preliminary study to study the distribution of rainfall, discharge, and hydrological engineering for development in Benowo area, Surabaya.
