The problem originated in the late 19<sup>th</sup> century with William Morris Davis who is sometimes called the father of geomorphology and was one of the first geologists to interpret what in the late 19<sup>th</sup> century were newly available topographic maps. An 1889 Davis paper describes selected drainage system evidence observed on an advance copy of the 1890 Doylestown (Pennsylvania) topographic map and an 1892 Ward paper written after discussions with Davis describes additional selected drainage system evidence seen on the same map. Both papers fail to mention the majority of the Doylestown map’s drainage system features including most barbed tributaries, asymmetric drainage divides, and through (dry) valleys crossing major drainage divides. Had Davis used all of the map’s drainage system and erosional landform evidence he should have recognized the map evidence shows headward erosion of an east-oriented Neshaminy Creek valley captured southwest-oriented streams which headward erosion of the south-oriented Delaware River valley and its east-oriented tributary Tohickon Creek valley had beheaded. Consciously or unconsciously, Davis chose not to alert future investigators that Doylestown topographic map evidence did not support his yet-to-be-published Pennsylvania and New Jersey erosion history interpretations and instead Davis proceeded to develop and promote erosion history interpretations which the map evidence did not support.展开更多

Therefore, in the specific construction stage, people pay more and more attention to engineering geological investigation. Hydrogeology is a very important and indispensable link in engineering geological survey, but it is also easy to be ignored. If the site hydrogeological conditions are not clear during the survey, the groundwater is likely to damage the proposed building and ultimately affect the normal use of the building. Environmental geological survey is one of the preparatory work before the construction, which directly affects the quality management of the project. The geological and hydrogeological environmental factors of the construction site have a great impact on the construction of the project, so the geological exploration before the project starts is very important. Therefore, this paper hopes to provide reference for the work of relevant personnel through the study of engineering geology and construction engineering hydrogeological investigation.展开更多

With the acceleration of reform and opening up, the number of modern buildings is increasing, and the number of modern water-saving projects is also increasing year by year. Therefore, it is particularly important to study the hydrogeology and the engineering geology around the structure before the project construction, and it is very important to combine the hydrogeological exploration with the engineering geological exploration. This paper expounds the concept of hydrogeology and engineering geology, and analyzes its practical application, in order to provide a reference value for the relevant personnel.展开更多
