假期没有出去玩，一个人在家休息。

 

因为有一个新的海绵城市项目，又要用到EPA SWMM这款软件建立海绵城市的基础模型，网上搜索资料时发现EPA SWMM又发布了最新的版本- SWMM 5.1.015，所以把它下载下来安装，打算用来建立海绵城市SWMM模型。

 

 

先看一下SWMM 5.1.015版本更新了哪些内容，也好在新的模型中做出相应的处理。

 

以下是epaswmm5_updates.txt的注释

SWMM 5.1 Update History

SWMM 5.1 更新记录

 

————————-

Build 5.1.015 (July 2020)
SWMM 5.1.015 (2020年七月)完成

 

SWMM 5.1.015是在SWMM 5.1.014的基础上更新的，下面看一下SWMM 5.1.015做了哪些更新。

 

————————-

Engine Updates:
计算引擎更新内容：

 

1. A mix of infiltration methods can now be used within a project.
1. SWMM 5.1.015版本增加了混合渗透模型功能，模型中的子排水区（或者叫子排水区，下同）可以单独选择渗透模型，也可以使用系统统一的渗透模型。

 

下面两张图是SWMM 5.1.014和SWMM 5.1.015中渗透模型选项功能的界面对比。

 

 

2. Monthly adjustments to depression storage are now applied only to the pervious area of subcatchments instead of to both pervious and impervious areas.
2. SWMM 5.1.015版本规定洼地蓄水量月份调整功能只能用于子集水区的透水区域，而不是用于全部的透水区域和不透水区域。

 

如果不进行多年长历时的模拟，SWMM模型中洼地蓄水量月份调整功能不是很重要。

 

SWMM软件的HELP说明
Dstore Pattern Name of optional monthly Time Pattern adjustments applied to both depression storage (Dstore) values. Leave blank if not applicable.
Time Patterns allow external dry weather flow (DWF) to vary in a periodic fashion. They consist of a set of adjustment factors applied as multipliers to a baseline DWF flow rate or pollutant concentration. The different types of time patterns include:
Monthly one multiplier for each month of the year.
Daily one multiplier for each day of the week
Hourly one multiplier for each hour from 12 AM to 11 PM.
Weekend hourly multipliers for weekend days.
Each time pattern must have a unique name and there is no limit on the number of patterns that can be created. Each dry weather inflow (either flow or quality) can have up to four patterns associated with it, one for each type listed above.
Monthly time patterns can also be used to adjust the baseline values of the following hydrological parameters:
• subcatchment depression storage
• subcatchment pervious surface roughness
• soil infiltration recovery rate

 

3. The Status Report now includes a grouped frequency table of the variable routing time steps used during a simulation.
3. SWMM 5.1.015版本的状态报告增加了分组频率表单函数，该函数可以打印模型运行过程中时间路由内各时间步长的分组频率表单，该分组频率表单是采用模型统计数据进行二次处理的。

 

该函数的目的：将时间路由内各时间步长的分组频率表单写入.rpt文件。

 

 

4. An error in the average summary statistics reported for projects with a reporting start date later than the simulation start date was fixed.
4. SWMM 5.1.015版本修复了数据平均汇总统计报告中，报告输出开始日期晚于模型运行开始日期的错误。

 

5. A fatal error is now issued if a storage node’s area curve produces a negative volume when extrapolated to the node’s full depth.
5.当节点出现溢流时，如果一个蓄水节点的面积曲线中由出现负体积则系统会发出一个严重错误的提示。

 

6. A pollutant mass balance error occurring when very shallow storage units lost all inflow to flooding was fixed.
6. SWMM 5.1.015版本修复了水位非常浅的蓄水单元中所有入流量转变为涝水时产生的污染物质量平衡误差。

 

7. Conduit evaporation and seepage losses are now applied directly to the conduit’s flow rate instead of just to the downstream node’s inflow to reduce water quality mass balance errors.
7. SWMM 5.1.015版本中沟渠的蒸发和下渗损耗直接应用于沟渠的流速，而不只是下游节点的入流量，目的在于减少水质质量平衡误差。

 

8. Spurious values appearing for Final Water Table and Upper Mositure Content in the Groundwater Summary Results Table for completely impervious subcatchments were corrected.
8. SWMM 5.1.015版本纠正了完全不透水子集水区的地下水汇总结果表里面最终水位和上层土壤含水率数据中出现的伪数值。

 

GUI Updates:
用户界面更新内容

 

 

1. The mouse wheel can now be used to zoom in or out of the Study Area Map and when pressed be used to pan the map.
1. SWMM 5.1.015版本用户界面增加了鼠标滚轮的功能，可以在地图的任意区域滑动鼠标滚轮对地图进行放大或缩小。

这个功能实在时太方便了，和CIVIL 3D的Autodesk® Storm and Sanitary Analysis一样方便。

 

2. The Subcatchment Infiltration Dialog was modified to accept a choice of infiltration method.
2. SWMM 5.1.015版本的子集水区渗透模型选项面板运行子集水区单独选择渗透模型，这个在前面讲过了，查看前面的图片。

 

还是再发一次图片吧

 

3. The Group Editor dialog was modified to allow a choice of infiltration method and its parameters be assigned to a group of subcatchments.
3. SWMM 5.1.015版本优化了批量编辑面板的选项，允许用户对子集水区的渗透模型进行批量选择，软件会将选择好的参数批量关联到对应的子集水区。

 

这个功能也时十分便利的，再SWMM 5.1.015版本之前的版本中是没有的。

 

4. The Control Curve assigned to an LID unit’s drain layer was being ignored by the input file reader.
4.当用户在LID Control Editor面板中给一个LID单元的排水层指定参数时，文件读取器将忽略关联LID单元排水层的控制曲线。

 

 

SWMM help中Control Curve详解
Control Curve
The name of an optional Control Curve that adjusts the computed drain flow as a function of the head of water above the drain. Leave blank if not applicable.
Control – determines how the control setting of a pump or flow regulator varies as a function of some control variable (such as water level at a particular node) as specified in a Modulated Control rule. Is also used to adjust the flow from an LID unit’s underdrain based on head.

Each curve must be given a unique name and can be assigned any number of data points.

 

5. Some problems with the Graph Options dialog for the Statistics Report plots were fixed.
5. SWMM 5.1.015版本修复了用于生成统计报告图的图形选项面板的若干问题。

 

6. Better support for 4K ultra HD monitors was added.
6. SWMM 5.1.015版本能更好的支持4K超高清显示器。

 

7. The latter update required that the three toolbars on the main window be combined into one to avoid resizing issues.
7. SWMM 5.1.015版本界面新增了响应式功能，将此前版本中主窗口上方的3个工具条合并成一个工具条，工具条可以随软件界面大小自动调整位置了，避免了SWMM 5.1.014、SWMM 5.1.013等此前版本中3个工具条自适应界面能力差的问题。

 

下面对比一下SWMM 5.1.014版本和SWMM 5.1.015版本中工具条的自动调整方式。
